Ramadan Moon Sighting 2023: The International Astronomical Center (IAC) announced the sighting of the crescent moon marking the beginning of Ramadan. The observation took place on Wednesday at 8:15 am in Abu Dhabi. This means today, March 23, is the first day of Ramadan. At 10:30 am (UAE time), the centre captured a clearer image of the Ramadan crescent. Due to the increasing distance between the moon and the sun and the horizon, the view is clearer.
